| Slawek Kaplonski | 2023-07-27 13:46:45 UTC | Doc Text | Cause: North-South traffic in vlan/flat tenant networks is distributed when Floating IPs are used. Consequence: This is causing issue with Floating IP port forwardings associated with Neutron ports connected to the vlan or flat tenant networks as traffic to/from port forwardings needs to be centralized on the controller (networker) node. Workaround (if any): To make Floating IP Port Forwarding to be working fine, either set "enable_distributed_floating_ip=False" in the Neutron configuration or use Geneve tenant networks intead of vlan/flat networks is required for now. Result: Floating IP port forwarding will be working fine through centralized gateway node. | |

Result: Floating IP port forwarding will be working fine through centralized gateway node. | In RHOSP 17.1 GA environments that use the ML2/OVN mechanism driver, there is a known issue with Networking service (neutron) ports connected to VLAN or flat project networks not properly forwarding floating IP (FIP) traffic. This problem is caused because VLAN and flat networks distribute north-south network traffic when FIPs are used, and instead FIP port forwarding should be centralized on the Controller or the Networker nodes. + Workaround: To resolve this problem and force FIP port forwarding through the centralized gateway node, either set `enable_distributed_floating_ip=false`, or use Geneve instead of VLAN or flat project networks. |
